  • FIG. 1 is a side elevational view partially in vertical section of the charging end of a glass annealing lehr showing ware transfer mechanism for delivering the Ware from the forming machine conveyor to the lehr conveyor;
  • FIG. 2 a side elevation of the discharge end of the lehr of FIG. 1 at and beyond the cooling section showing ware transfer mechanism for delivering the ware to theinspection and packing table;
  • FIG. 4 as applied to the multiple tunnel lehr of FIG. 3
  • FIG. 3 a longitudinal section of a multiple tunnel lehr with conveyor strands moving in opposite directions and transfer mechanisms for moving the ware from one strand to another, out of contact therewith during the transfer movement;
  • FIG. 4 a top plan view of the transfer mechanism of the multiple tunnel lehr of FIG. 3;
  • FIG. 5 a vertical section partially in elevation of the transfer mechanism of FIG. 4 taken on the line 5-5, FIG. 4;
  • FIG. 6 a side elevational view partially in section of the gripping jaw mounted on a sprocket chain for engaging the bottles taken on the line 6-6, FIG. 4;
  • FIG. 7 a top plan view of a straight line transfer mechanism for disengaging the ware from its conveyor support and holding it in suspension for spraying the bottom of the ware;
  • FIG. 8 a side elevation partially in sections taken along the line 8-8, FIG. 7.
  • FIGS. 1 and 2 placed end to end show the charging and discharge end of the lehr.
  • the numeral 10, FIG. 1 designates a conveyor that delivers the bottles, 11, from a ware forming machine (not shown) to a transfer mechanism, 12, of the type shown in FIGS. 7 and 8 by which it is transferred to the conveyor belt, 113, of a glass annealing lehr generally designated by reference character 14.
  • the front or charging end of the lehr, 15, has a series of fire boxes, 16, below the conveyor, 13, and preheating chamber, 17, to preheat conveyor belt, 13-.
  • Radiant cup burners, 18, are provided in the roof, 19, of the front heating section to rapidly bring the temperature of the Ware to the annealing range and the temperature gradients to which the ware is subjected is controlled by the successive independently controlled temperature zones or sections as described in my Pat. No. 3,601,375 granted Aug. 24, 1971, and Pats. No. 3,010,710' and No. 3,261,596.
  • bottles are transferred from the forming machine conveyor belt, 10', to the annealing lehr conveyor, 13, by transfer mechanism, 12, they are suspended to expose the bottom to lubricating sprays, 20 and 21, to protect them from abrasive contact when engaged by conveyor belt 13.
  • the treating zones of lehr 14 consists of sections 14a, 14b, 14c, and 14d, as many as are needed for the kind and size of ware to be treated at a given speed of the conveyor 13.
  • the rapid cooling section, Me is described in my Pat. No. 3,371,430.
  • a lubricating spray, 23 is then applied as shown in FIG. 2.
  • a spray, 24 is applied to the sides of the bottles to reduce or eliminate abrasive contact.
  • the conveyor drive drum, 25, is driven by motor 26 through transmission 27.
  • the spraying after annealing is at a lower temperature than spraying at the charging end of the lehr.
  • a drum, 35, having a resilient surface, 36, for engaging bottles, 11, is driven by motor 37 through sprocket wheels 38 and 39 and spindle 40.
  • the sprocket chain is driven by a motor not shown that drives spindle 41.
  • the speeds of conveyors 28 and 29 and sprocket chain 31 and drum 35 are synchronized to be substantially at the same peripheral speed.
  • gripping pads, 42 are mounted on links, 43, of chain 31 and are supported on spring mounts 44 having flanges 45 engaging grooves 46 to grippingly engage bottles, 11, to suspend them as they pass around drum 35 as shown in FIG. 5. Should any glassware be upset during passage through transfer mechanism of FIG. 4, it will fall off conveyor 28 into a receptacle, 47, as shown in FIG. 5.
  • a circular track, 48, FIG. 5, is engaged by followers, 49, to guide the gripping elements, 42, in spaced relation around drum 35 to hold the ware in suspension as shown in FIG. 5.
  • a pair of endless conveyor chains, 50 and 51 are mounted on sprocket wheels, 52, 53, 54, and 55.
  • Wheels 55 and 53 are driven by motors 56 through sprocket chains 57.
  • a single spray nozzle, 58 is shown to spray the bottom of the ware while suspended instead of two in FIG. 1 wherein a single spray nozzle, 59, is shown above the ware to spray the side of the bottles.
  • two side spray nozzles, 60 and 61 are shown. Unless a long chain of gripping members is required the tension of the gripping chains will maintain alignment of the gripping members for engaging the bottles as shown.
  • FIG. 3 The employment of parallel multiple tunnel lehrs, shown in FIG. 3, has been deferred because of the inability to efiiciently transfer the ware from one conveyor to the adjacent conveyor.
  • FIGS. 4 By means of the transfer mechanisms of FIGS. 4 and which is diagrammatically shown in FIG. 3, the ware is out of abrasive contact when transferred from one to another of the conveyors and the multiple tunnel lehr is now available where space is a factor.
  • the conveyor strand 64 extends outside the lehr housing, 63, for receiving the ware, and conveyor strand 62 extends out of the housing at the exit end 65.
  • the center tunnel is open at both ends to communicate with both transfer mechanism as shown.
  • the ware may be subject to check detection top and bottom without interrupting the continuity of movement by placing check detector equipment in the path of movement of the ware by the transfer mechanism and the bottles can be rotated when going through the transfer mechanism by simply operating one side of the gripping means at a different speed than the other.
  • the ware could also be labeled without interrupting its movement through the sprays by rotating the ware when one end of the label has been applied.
  • a tunnel shaped chamber comprising heating and cooling sections
  • said transfer mechanism engaging the articles in a manner to expose the bottom of the articles in their travel between adjacent conveyors.
  • a tunnel shaped chamber comprising heating and cooling sections
  • said transfer mechanism engaging the articles in a manner to expose the bottom of the articles in their travel between adjacent conveyors.
  • a spray for coating the sides of the article is provided in the path of movement of the articles on the delivery conveyor.
  • An industrial heating furnace as set forth in claim 1 further including a spray for coating the sides of the article, said spray being in the path of movement of the article on the receiving conveyor.

  • said conveyor means being spaced apart and syncho nized to move at substantially the same speed
  • a gripping mechanism of articulate clamping members for engaging one side of the ware mounted on an endless chain having sprocket wheels at opposite ends of the space between said conveying means
  • clamping members being connected to the chain by spring means to grippingly engage the ware to suspend it out of bottom contact with said conveyor means during the ware transfer movement.
  • the endless tracks of clamping members are juxtaposed to form an uninterrupted path of travel of the ware in alignment with the conveyor means.
